BUTTON.

SPECIFICATION forming part of Letters Patent No. 308,630, dated December 2, 1884.

Application filed February 1S, 1884. (No model.)

To all whom, it may con/cern:

- Beit known that we, .Litres B. RroiiARDsoN and SILAS J. ALLEN, both citizens of the United States, residing in the city and county of Providence, in the State of Rhode Island, have invented certain new and useful Improvements in Sleeve and Collar Buttons and Studs, of which the following is a specification.

Our invention relates to t-hat class oi' buttons and studs in which there is a curved oscillating post actuated by a spring to automatically interlock with an oppositelycurved stationary post, and it consists in the construction and assemblage of theseveral parts of the button.

It has heretofore been customary to construct the back-plate of the button in two parts and solder the part containing the operative parts to the :main portion of the backplate; and the oscillating post and its actuating-spring have been heretofore jointed and 4the back-plate, to avoid breakage under the strain oi the operative parts ofthe button, and

to facilitate and cheapen the cost of nianufacn ture, all of which we attain by the construetion and arrangement shown, and hereinafter described.

Referring to the accompanying drawings, Figure l is a plan of the back-plate. Fig. 2 is a section of the same in elevation on line y y. Fig. 3 is a side view of the stationary post. Fig. 4 is a perspective view of the stationary post. Fig. 5 is a perspective view of the oseillating post. Fig. 6 is an elevation of the same. Fig. 7 is a plan of the retaining-disk. Fig. S is a plan of one form of the actuating' spring. Fig. 9 is an elevation in cross-section, showing the several parts assembled, the dotted lines indicating the movement and position of the oscillating post in unlocking the button for removal from the garment; .and Fig. 10 is a section of the plate shown in Fig. 7.

Similar letters indicate similar parts, where they occur in the drawings.

A represents the baek-plate, which may be of any desired outline, and itis provided with a recessed chamber, A2, depressed more deeply on one side than 011 the other. This chamber A-`z has still deeper recesses, A3, located at each end of a central orifice, A. The back-plate, A, is struck up from a single piece of stock, the chamber A2, recesses A, and slot A all being formed at the same time. In striking it out we leave the corner pieces, d d, on one side of the orifice or slot A and enlarge the orice on the opposite side, as at u.

E is a post, which is struck or cut from a single piece of stock, and having the part E and open side slots, o o. The part E is bent at right angles to the body of the post adjacent to the slots o o, and the foot of the post is bent inthe opposite direction, as shown in Figs. 3 and 4. Vhen the part E is inserted through the orifice A', the part E' iits into the deeper` part of the recess A, and the open side slots, o o, receive and engage the corners cl d ot` the back plate, imparting more rigidity to the post, which also may be riveted, soldered, or otherwise secured to the back-plate.

It will be observed that after the insertion of this part E in the deeper side of the chainber A2 there vdwill then remain a chamber of uniform depth divided centrally by theori ce A and recesses A Ai. v

D is a curved post open-slotted atm, slotted at 7c, and notched at m. It is cut from asingle piece of stock to leave the journals or trunnions a a, and is then bent into the form shown in Fig. 6. These journals or trunnions aafit into the recesses A3 A3 in the back plate when the post D is inserted in the oritice A. The spring s is coiled with two oppositelyextended ends, as shown in Fig. S.

Ve do not coniine our invention to the specie forni of spring here shown.- Any coil or spiral spring can be used to equal advantage, as can also a dat or strap spring, except that, in case the fiat spring were used, we would recommend omitting the open slot m in the post, so that the spring would bear across the entire end ofthe same.

' B is a disk, which is struck from a single piece of stock and provided with the raised lugs c c and the recessed chamber b b. This disk B retains the operative parts of the button in place. The raised lugs c c and recessed chamber b b', being struck up from the body IOT) of the disk, act, respectively, to retain the post D in the sockets A3 A3 and to forrn a chamber for the spring s, which is arranged to lie partly in the chamber b and partly in the open slot m of the post D, with one arm engaging the notch a" in the post and the other arm lying between the back plate, A2, and the disk B in the recess b. The post D is thus hinged on the inner faces of the recesses A3 A, and no securing-pin is required vfor it or the actuatingspring.

In practical manufacture of our invention, the several parts being constructed substantially as shown and'described, the post D is passed through the oriiice A until its trunnions a ce fall into the recesses A3 A3. The post E is then passed through the oriiice A and slot k in the post D until the disk E fits into the deeper portion of the chamber A2, and the side slots, o o, engage the corners d d, and the disk is then riveted, soldered, or otherwise ilnniovably secured to the back plate, affording a rigid fixed post. Then, if the actuatingspring is of the form shown in the drawings, it is made to enter that part ofthe orifice A unoccupied by the posts at n, so that one of its arms will extend outwardly through the oriiee A and engagefthe notch x in the post D, while the other arm will be retained in position along the bottom of the chamber A2 by the disk B, secured to the back plate, so that the spring will lie in the notch m oi' the post D partly, and partly in the recess b of the disk B, and the raised lugs c c willvform bearing-surfaces, against which the trunnions ce a will work when the post D is oscillated to lock and unlock the button. The back plate then can be inserted in the rim of the button in the ordinary manner.

Modifications as to the form and proportions can be readily made by any good mechanic Without departing from the principle or detracting from the utility oi' our invention.

XVe claim as our inventionl. rllhe combination ofthe back-plate A, provided with the unequally-recessed chamber A2 and projected corners d d and depressed recesses A3 A3, with a post, E E', oppositelycurved post D, slotted at k and fm and notched at x, and provided with trunnions a a, a Spring, s, adapted to actuatc the postD automatically, to lock the button, as shown, and a retainingdisk, B, provided with raised lugs c c and chamber b b', all arranged and operating substantially as shown and described.

2. In a button and stud, a back-plate, A, provided with an unequally-recessed chamber, A2, orifice A', with its inteijected corners d d, depressed recesses A3 A3, all struck and cut from a single piece of stock, as shown, in combination with a retaining-disk, B, struck from a single piece of stock, with the recessed chamber I) b and the projecting recessed lugs c c, as shown.

3. In a button and stud, the combination of a post, E, having a part, E', and the adjacent open side slots, o o, all struck from a single piece oi' stock, as shown and described, the

said part E and the foot of the post being turned at right angles to the body of the post and oppositely to each other, with a post, D, provided with open slot m and notch x at the end,'and slot k and trunnions a a., forming an integral part of the post, and all struckfrom a single piece of stock, as shown and described.

In testimony whereof we have hereunto Set our hands this 16th day of February,`A D. 1884.
